-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Juan, now I understand better what is going on. So before going to bed: please correct me if I'm wrong: * You had a working GNU Radio + UHD installation that suddenly stopped working last week * You installed this from the Ubuntu packages (?) * Then you tried different source builds of GNU Radio and all crashed.
I don't know what caused this, but it could be a compatibility issue between UHD headers and binary libraries. In this case, the first step would be to make sure you have a clean system: please uninstall all uhd and gnuradio builds and binaries and try to make sure none of these installations linger. Then: decide whether you want to go the self-built route or the binary route. This decision might depend on the version of GR you want to use: if you want to learn GNU Radio, use 3.7, but if you need to support older code, you might want to go for 3.6.; you can't use modules designed for 3.6 with 3.7. Install then UHD + GNU Radio either from your package directories, or install and build UHD und GNU Radio using pybombs simultaneously.
